Description

Anti-corrosion structure of ceramic anilox roller

Technical Field

The utility model relates to an anilox roller technical field specifically is a corrosion protection structure of pottery anilox roller.

Background

Ceramic anilox rolls (hereinafter referred to as anilox rolls) generally adopt metal materials as a matrix, and conventional matrix materials are carbon steel and aluminum alloy, so that the problem of corrosivity is faced. Besides the self corrosion, the anilox roller is corroded by ink, solvent and cleaning agent in the use process, and as the base material is corroded, the surface of the anilox roller is deformed and fails, so that the product is scrapped.

The anilox roller is subjected to surface treatment by thermal spraying, and Plasma spraying (APS and Plasma spraying) is conventionally adopted, however, coatings prepared by the process (such as chromic oxide, aluminum oxide and titanium aluminum oxide) are of a layered stacking structure, irregular tiny pores inevitably exist in the coatings of the process, and corrosive media (electrolyte solution) such as ink solvent and the like can gradually penetrate and contact the surface of the substrate through the pores, so that electrochemical reaction is formed, the surface of the substrate is corroded, the combination of the substrate and the coating is damaged, and the deformation failure of the roller surface coating is generated.

SUMMERY OF THE UTILITY MODEL

For solving the above-mentioned problem that the background art provided, the utility model provides an anticorrosion structure of pottery reticulation roller.

In order to achieve the above purpose, the utility model provides a following technical scheme: the utility model provides an anti-corrosion structure of pottery reticulation roller, includes metal roller base, sets up the first composite bed in the metal roller base outside, sets up the second composite bed in the first composite bed outside, first composite bed includes metal transition layer and forms the first hole sealing layer on metal transition layer surface, the second composite bed includes ceramic coating and forms the second hole sealing layer on ceramic coating surface.

Preferably, the material of the metal transition layer is nickel-chromium alloy.

Preferably, the material of the ceramic coating is one of chromium oxide, aluminum oxide or titanium aluminum oxide.

Preferably, the material of the metal roller blank is one of carbon steel or aluminum alloy.

Preferably, the thickness of the ceramic coating is 0.25 mm.

Compared with the prior art, the beneficial effects of the utility model are as follows:

the utility model provides a corrosion protection structure of ceramic reticulation roller, first composite bed and second composite bed are composite construction, and the intraformational through-hole of metal transition can be sealed on the first hole sealing layer of first composite bed, and the intraformational through-hole of ceramic coating can be sealed on the second hole sealing layer of second composite bed, and external environment corrosion is not received to the protection reticulation roller product.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1, the utility model provides an anticorrosion structure of pottery reticulation roller, including metal roller base 1, set up first composite bed 2 in the metal roller base 1 outside, set up the second composite bed 3 in the first composite bed 2 outside, first composite bed 2 includes metal transition layer 21 and forms the first hole sealing layer 22 on metal transition layer 21 surface, second composite bed 3 includes ceramic coating 31 and forms the second hole sealing layer 32 on ceramic coating 31 surface. Meanwhile, the material of the metal transition layer 21 is nichrome, the material of the ceramic coating 31 is one of chromium oxide or aluminum titanium oxide, the material of the metal roller blank 1 is one of carbon steel or aluminum alloy, and the thickness of the ceramic coating 31 is 0.25 mm.

Irregular tiny pores exist among all layers of the ceramic anilox roller, the pores of all layers can form through holes penetrating through a metal transition layer and a ceramic coating, corrosive media such as ink solvents and the like can gradually permeate and contact the surface of a metal roller blank through the through holes to corrode the metal roller blank, so that a hole sealing agent is coated on the outer surface of the ceramic anilox roller during production, the hole sealing agent is composed of Alkoxy Silane (Alkoxy Silane) polymers, functional groups of the hole sealing agent react with moisture in the air after coating to form inorganic polymers and harden, the pores are blocked, and the influence of an external environment on the ceramic anilox roller is prevented.

Specifically, the sealant flows to the surface of the metal transition layer 21 through the opening to seal the through holes in the metal transition layer 21 and form a first sealing layer 22 on the surface of the metal transition layer 21, and the sealant seals the through holes in the ceramic coating 31 and form a second sealing layer 32 on the surface of the ceramic coating 31.

Meanwhile, the first hole sealing layer 22 and the second hole sealing layer 32 have high-strength adhesive property after being cured, and cannot be peeled or fall off during subsequent product processing and manufacturing, so that the micropores of the coating can be permanently sealed, and corrosion of corrosive media can be prevented.

It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
